That doesn't really look like varnish to me, just oil staining. Varnish is more a dark brown or reddish sticky goop.
what 20k oci looks like

Me too. Varnish is opaque and in the images you can clearly see through the color to the metal underneath. I'd consider that top end to be super clean for 20k OCI.
nope
this is the special edition ultra thin rose gold varnish not the normal brown kind
I think the last "real" Jags were the ones made before Ford bought them and managed to build even worse cars than the last "real" Jags.
you ever driven a series 2-3 xj or any early XJS? they suck. ford stepped in and saved the company, they made very good cars in just a few years.
their departure and the resulting permanent marriage with land rover killed them for good

Well, Ford owned Aston Martin for a while, as well as Jaguar and, I believe, Land Rover.
So I guess Chinese (Volvo) or Indian (Jaguar)?
Is varnish harmful to the engine?
Varnish: Is it really harmless?
One thing I've noticed is that on almost any engine that has had some sort of failure, there is always varnish present. Many will and have argued on this board that varnish is harmless. I'm not so sure about that. A recent thread on Maxbimmer, where a gentleman's M62 had its timing chain guide...

Based on the mileage I'm thinking Lexus. GS300?
He told us a jaguar last night. I misread his hints, butttt. I never knew jags were running straight 6's and I also was surprised they supercharged those monsters, ~367hp w `470 tq. Must be fun to drive!
Thats an angry motor
To me it wouldn't make sense if a company made a V12 and no straight 6.
Today I learned that Jag's made V-12's up until '97. Thought they killed those in the early 80's.
Where I am no way I can go 20k miles without oxidative thickening. Even 10k km is pushing it. Not sure why.
I remember seeing a supercharged I6 were the specs were ridiculous in the 400's, must have stumbled into a different I6 engine... Like the BMW I6.
sounds like you have mediocre fuel and/or oil
here we are lucky to have cheap flagship oils and relatively decent gasoline
We dont have e85. its all 100% gasoline, could this be the cause ? Oil wise pretty sure we are using the same stuff. I use euro Shell 5W40.
In the US the gasoline now has to be refined to a similar standard as Europe with very little sulfur in it, in other parts of the world gasoline may still be allowed to contain very high levels of sulfur.
